Tinder

Char cloth can be made by placing plant-based fabric (usually cotton) in a tin box into a campfire; like charcoal, it is the product of anhydrous pyrolysis.

The parts of the deadwood that would form the knots in lumber, i.e. the places where branches entered the trunk, are impregnated with resin which has the combustibility of wood soaked in lighter fluid.

These stumps contain spires of resin-impregnated wood, called fatwood, which can easily be lighted using only a single match or lighter.

[3] Embers of burned paper, leaves and other sheetlike materials are easily carried off by air currents, where they can alight upon other objects and ignite them.

Shavings burn white-hot, are impossible to smother with carbon dioxide or sand, and can ignite even wet kindling.

Solid bars are impossible to ignite under normal conditions (and difficult even with a welding torch), and are thus very safe to carry.
